SOUND IRECGIBI)ING:A AND REPRODUCING MACHINE.

Application filed June 1, 1917.

To all whom 'it may concern:

Be it known that we,DA\'1D FREDERICK MC- QUIRE and KENNETH DOUGLASMCQUIRE, both subjects of the King of 'Great Britain and Ireland, andboth residing at Braemore, Herbert Road, Hornchurch, in the county ofEssex, England, have invented certain new and useful Improvements inSound Recording and lReprodu'cing Machines, of which the following is aspecification.

This invention relatos to sound recording and sound reproducing machinesemploying disk records and of the type adapted both for the recording 0fsounds and for the rcproduction of sounds thus recorded, the inventionbeing principally adapted for domestic and oiiice use.

The object of the present invention is to provide an improved form ofmachine of the above character in which the reproduction of therecordedsounds may be effected through the usual tone arm, sound chamber oramplifyinghorn without damage to the record, due` tothe fact that byreason of our construction the recording stylus or like member and thereproducing member both move across the face of the record in the samepath instead of as is usual the one member moving in a rectilinear pathand the other in a curved path.

The invention consists in a sound recording and sound reproducingmachine comprising in combination a record supporting member, a tonearm, a member movable rectilinearly across the face of the record andmeans connecting the tone arm with this latter member but slidable uponsaid member.

The invention also comprises a sound recording and sound reproducingmachine of the above character having a carrier for the recorder andreproducer, rotatable about a vertical axis, so that either the recorderor reproducer may be moved into its operative position.

The invention further comprises other de! of device in accordance withthe invention Speciication of Letters Patent.

Fig. 2;

Fig. 11 is a view showing a detail; while Fig. 12 is a view illustratinga modified form of reproducer.

In carrying our invention into e'ect in one convenient manner as, forexample, in its application to a machine of the gramophone type, weprovide the usual turntable a driven by any suitable motor (not shown)and Vlocated within a cabinet b if desired. Upon the cabinet orframework t we mount a pillar c (or the same may be independentlymounted) and upon this pillar or support c' and a socket J upon thespindle e of the turntable we arrange a tubular or other carrier fadapted to support a sleeve or like member g and. provided with suitablemeans for moving the sleeve or the like longin tudinally or axially. Forexample, the sleeve or the like g may be fitted with a half nut (notshown) adapted 'to engage a longitudinal screw t driven from theturntable by shaft z' and bevel gearing la and fitted with any usualform of half1 nut or other quick release actuated by the milled head orother member Z, substantially as shown 1n English patent of Thoshann,22,268 of 1914, this subject matter forming per. se no part of thepresent invention.

The sleeve g is encircled by a second and shorter sleeve m', which isrotatably mounted thereon, the amount of rotationl of the sleeve beinglimited by a projection m2 on the sleeve coperating with the upper partof the guide bracket :v and this sleeve m carries a bar m. By rotationof the sleeve 1n the .proper direction the bar m may be swung verticallyfrom the position Shown in full.

' lines, the bar by means of its sleeve being capable of being rotatedinto the position shown by the dotted lines in Fig. 1 when it is desiredto clear the machine or otherwise disconnect, or vice versa.

A member n has a forked lower end n which straddles the outer end of thebar m and t0 the member n is connected a clamp or support 0, whichencircles the tone arm.

A convenient manner of effecting this adjustable connection is toprovide the clamp o with an angularly turned upper end o to which isconnected the lower end of a screw rod e' and which has an extension o2working in a lvertical slot or bifurcation in the member n. A spring atends to force the angular bent part 0 in a downward direction, while itmay be drawn upwardly against the tension of the spring by a milled nut22 bearing against the upper face of a bracket member 'n2 supported bythe member n. The bar m thus supports the weight of the tone arm p orother member carrying the recorder g and reproducer 11, and when inoperation ment to the tone arm.

The clamp 0 heilig adjustable vertically permits of the use of recordingblanks of different thicknesses and also provides for wear of the blank,while at the same time f communicates the necessary traversingmoveenabling the recorder and reproducer alwaysv to be. properlypositioned to fulfil their respective functions.

It will be understood that the recorder and reproducer may be removableand may be .separately carried upon the machine when requiredrespectively for recording and reproducing, but for convenience weprefer to carry both simultaneously upon the machine and provide meansfor throwing the one not required at the time out of action.

One method of attaining this object is shown in Fig. 2 according towhich there is fitted to the socket of the tone arm p a. fitting s upona tubular extension t to which the recording horn u (Fig. 6) is mounted,the fitting having a second tubular extension v provided with anaperture 'w and mounted within an outer rotatable sleeve carrying therecorder and repoducer. The arrangement is such that the sleeve may berotated about a vertical axis through 180, and the recorder andreproducer may be raised or lowered slightly by means ofthe spring armsor levers 4 which are provided each witha recessed end adapted to beengaged with one or the other of a pair of studs 5 in order to hold therecorder or reproducer in its raised position, so that either may bebrought into position for operation and in register with the aperture wcommunicating with the interior of the fitting s in such a manner as tocommunicate with the recording` horn or. with the amplifying horn orusual way with the tone arm p. When the recorder is thrown out ofoperation a plug z may be introduced into the tubular extension t to cutout the recording horn.

It will be seen that with such an arrangement as that above describednot only will the weight of the device carij'ing the recorder andreproducer be adequately supported sothat the tone arm with its addedweight may be employed for reproduction through the amplifying horn orchamber without fear of damage to the record, but also the necessarymovement may -be permitted to the recorder or reproducer and owing tothe combined movement of the device along the bar m and of the bar malong t-he carrier f, reproduction and recording take place along an areofthe same dimensions yin relation to the turntable.

Figs. 6 and 7 illustrate a modified form of arrangement 'which issuitable for use when the recorder and reproducer are to be carriedseparately upon the machine and not as above described simultaneouslyupon the machine and provided with means for rendering eitherinoperative as desired. In this case the fitting .s is .of somewhatsimilar form to that above described with the exception that it has nomovable sleeve on the lower extension. The latter is curved orvotherwise suitably formed to carry the reproducer r or the recorder g.The record.- ing horn u may be made to be reversible so that it may.either occupy the position shown in Fig. 6 or that shown in Fig. 8,reproduction in the latter case taking place partly through therecording horn or medium and partly through the amplifying horn orchamber while, as before, a suitable stop may be inserted in the upperportion t of the fitting s when reproduction is to takeplace through theamplifying horn or chamber alone.

When clearing the machine orv for other reasons it is desirable that thecarrier f should be raised so that the shaft z' may be disengaged fromthe socket d and the whole rotated about the axis of the pillar c, andfor this purpose a suitable arrangement is shown in F igs. 1 and 11 inwhich the pillar c is surrounded by a sleeve'l having a bayonet or anglesocket 2 engaging a stop or projection 3 upon the pillar, so that whenthe device is in the position shown in Fig. 1 the stop will be in thelowest portion of the socket 2, while whenthe device is required to bemoved out of the way it may be raised so 'that the stop comes on a levelwith the horizontal portion of the slot ywhich thus permits of therotation of the whole device about the axis ofthe pillarc through anangh of or of any other desired magnitu e.

Fig. 12 shows a modification in ,accord-V ance w1th the invention havingthe same general 'features as those above referred to but with amodified form of reproducer.

Having now described our invention what We claim as new and desire tosecure by lietters Patent is l.
